**Question:**
In paper chromatography, why do some ions move only a short distance from the point of application while others move much more?

**Explanation:**
In the process of paper chromatography, the movement of ions depends on several factors, including their affinity for the stationary phase (the paper) versus the mobile phase (the solvent). Ions with a stronger attraction to the paper will move less and travel a shorter distance. Conversely, ions that are more soluble in the solvent will travel further. Additionally, the size and charge of the ions can influence their movement; smaller or less charged ions may move more easily with the solvent compared to larger or more highly charged ones.
